三相異步電動機(jī)的缺相運(yùn)行是指三相供電電源缺少一相或三相繞組有一相從電源斷開而造成的一種電動機(jī)運(yùn)行狀態(tài)，三相異步電動機(jī)的繞組燒毀大多數(shù)是由于缺相運(yùn)行造成的。下面，我介紹一個(gè)簡便方法針對缺相故障進(jìn)行保護(hù)。一、對于星形接法電動機(jī)，由于三相交流電的失量和為零，其中性點(diǎn)對地電壓理論上為零，但實(shí)際上三相電壓不會平衡，總要相差幾伏電壓。當(dāng)電機(jī)缺相運(yùn)行時(shí)，由于定子三相電壓不平衡，中性點(diǎn)對地的零序電壓升高，當(dāng)電機(jī)滿負(fù)荷運(yùn)行時(shí)，此零序電壓可達(dá)達(dá)25～45伏。此時(shí)，可通過串接于電機(jī)中性線上的零序電壓繼電器來對電機(jī)進(jìn)行保護(hù)，如圖1所示。電機(jī)正常運(yùn)行時(shí)，中性點(diǎn)對地電壓較低，Kv不動作。，中性蘭對地電壓升高，使Kv動作，它的常閉觸點(diǎn)斷開而切斷KM線圈電源，隨即主電路斷電。二、對于定子繞組三角形接法的電機(jī)，可將星形接法的三只電容器(容量2～4uF為好)接于三角形繞組上，引出人為中性點(diǎn)，如圖2所示。由于實(shí)際電路中，中性點(diǎn)對地總有幾伏電壓，因此可以把電壓繼電器整定到12～24伏。此外也可使用市場上的小型中間繼電器(12或24伏)來代替電壓繼電器。這樣更方便些。濱州中型高壓電機(jī)廠商聯(lián)創(chuàng)電機(jī)熱情服務(wù)，確保產(chǎn)品質(zhì)量無后顧之憂。</p><div

style="text-indent:25px">異步電動機(jī)的氣隙是很小的，中小型電動機(jī)一般為0.2～2mm。氣隙越大，磁阻越大，要產(chǎn)生同樣大小的磁場，就需要較大的勵(lì)磁電流。由于氣隙的存在，異步電動機(jī)的磁路磁阻遠(yuǎn)比變壓器為大，因而異步電動機(jī)的勵(lì)磁電流也比變壓器的大得多。變壓器的勵(lì)磁電流約為額定電流的3%，異步電動機(jī)的勵(lì)磁電流約為額定電流的30%。勵(lì)磁電流是無功電流，因而勵(lì)磁電流越大。繞組是電動機(jī)的組成部分，老化、受潮、受熱、受侵蝕、異物侵入、外力的沖擊都會造成對繞組的傷害，電機(jī)過載、欠電壓、過電壓，缺相運(yùn)行也能引起繞組故障。繞組故障一般分為繞組接地、短路、開路、接線錯(cuò)誤。如今分別說明故障現(xiàn)象、產(chǎn)生的原因及檢查方法。</p><p style="text-indent:25px">三相異步電動機(jī)由固定的定子和旋轉(zhuǎn)的轉(zhuǎn)子兩個(gè)基本部分組成，轉(zhuǎn)子裝在定子內(nèi)腔里，借助軸承被支撐在兩個(gè)端蓋上。為了保證轉(zhuǎn)子能在定子內(nèi)自由轉(zhuǎn)動，定子和轉(zhuǎn)子之間必須有一間隙，稱為氣隙。電動機(jī)的氣隙是一個(gè)非常重要的參數(shù)，其大小及對稱性等對電動機(jī)的性能有很大影響。圖2所示定子由定子三相繞組、定子鐵心和機(jī)座組成。定子三相繞組是異步電動機(jī)的電路部分，在異步電動機(jī)的運(yùn)行中起著很重要的作用，是把電能轉(zhuǎn)換為機(jī)械能的關(guān)鍵部件。定子三相繞組的結(jié)構(gòu)是對稱的，一般有六個(gè)出線端U1、U2、V1、V2、W1、W2，置于機(jī)座外側(cè)的接線盒內(nèi)，根據(jù)需要接成星形（Y）或三角形（△），如圖3所示。圖3定子鐵心是異步電動機(jī)磁路的一部分，由于主磁場以同步轉(zhuǎn)速相對定子旋轉(zhuǎn)，為減小在鐵心中引起的損耗，鐵心采用0.5mm厚的高導(dǎo)磁硅鋼片疊成，硅鋼片兩面涂有絕緣漆以減小鐵心的渦流損耗。機(jī)座又稱機(jī)殼，它的主要作用是支撐定子鐵心，同時(shí)也承受整個(gè)電動機(jī)負(fù)載運(yùn)行時(shí)產(chǎn)生的反作用力，運(yùn)行時(shí)由于內(nèi)部損耗所產(chǎn)生的熱量也是通過機(jī)座向外散發(fā)。中、小型電動機(jī)的機(jī)座一般采用鑄鐵制成。大型電動機(jī)因機(jī)身較大澆注不便，常用鋼板焊接成型。為三相籠型異步電動機(jī)的組成部件。聯(lián)創(chuàng)電機(jī)愿與各界朋友攜手共進(jìn)，共創(chuàng)未來！</p><div

不但要對檢查中發(fā)現(xiàn)的問題及時(shí)采取補(bǔ)救措施，還要按保養(yǎng)周期（每月）對電動機(jī)進(jìn)行螺絲、接線緊固，拆解檢查、清潔保養(yǎng)等。如電動機(jī)端蓋4個(gè)固定螺絲全部松脫，會造成掃膛運(yùn)轉(zhuǎn)燒壞；電動機(jī)接線螺栓松動虛接造成缺相燒壞；電動機(jī)風(fēng)扇葉脫落抵住機(jī)體造成堵轉(zhuǎn)而燒壞；電動機(jī)軸承潤滑不良、運(yùn)行溫度高，而未及時(shí)補(bǔ)充潤滑油或更換軸承造成電動機(jī)燒壞；電動機(jī)因天氣潮濕絕緣電阻下降，不及時(shí)烘烤提高絕緣造成擊穿；工段內(nèi)電動機(jī)燒壞是因?yàn)闆]有及時(shí)檢查、緊固所致；還是因?yàn)殡m已發(fā)現(xiàn)問題，但沒做維護(hù)保養(yǎng)補(bǔ)救所致。無論是不看不做，還是只看不做，**終都會造成故障或。拆檢電動機(jī)時(shí)如需更換軸承，要盡可能用進(jìn)口的，國內(nèi)的會有不少是翻新的舊軸承，質(zhì)量難以保證。如發(fā)現(xiàn)軸承外圓與端蓋軸承座配合不緊密，即軸承走外圓時(shí)，要根據(jù)其程度不同，視情采用端蓋軸承座內(nèi)圈打麻點(diǎn)、墊銅皮或鑲銅套消除。一定要定準(zhǔn)中心點(diǎn)否則不久又會損壞。投入運(yùn)行前，要再次確認(rèn)軸伸出端徑向擺動與端蓋等緊固情況，轉(zhuǎn)子轉(zhuǎn)動是否靈活，繞組引線連接是否正確等等。聯(lián)創(chuàng)電機(jī)通過專業(yè)的知識和可靠技術(shù)為客戶提供服務(wù)。青島大型電機(jī)型號</p><p

style="text-indent:25px">異步電動機(jī)的轉(zhuǎn)子由轉(zhuǎn)子鐵心、轉(zhuǎn)子繞組及轉(zhuǎn)軸組成。轉(zhuǎn)子鐵心也是電動機(jī)磁路的一部分，也是用硅鋼片疊成。與定子鐵心沖片不同的是，轉(zhuǎn)子鐵心沖片是在沖片的外圓上開槽，疊裝后的轉(zhuǎn)子鐵心外圓柱面上均勻地形成許多形狀相同的槽，用以放置轉(zhuǎn)子繞組。轉(zhuǎn)子繞組是異步電動機(jī)電路的另一部分，其作用為切割定子磁場，產(chǎn)生感應(yīng)電勢和電流，并在磁場作用下受力而使轉(zhuǎn)子轉(zhuǎn)動。其結(jié)構(gòu)可分為籠型繞組和繞線式繞組兩種類型。這兩種轉(zhuǎn)子各自的主要特點(diǎn)是：籠型轉(zhuǎn)子結(jié)構(gòu)簡單，制造方便，經(jīng)濟(jì)耐用；繞線式轉(zhuǎn)子結(jié)構(gòu)復(fù)雜，價(jià)格貴，但轉(zhuǎn)子回路可引入外加電阻來改善起動和調(diào)速性能?；\型轉(zhuǎn)子繞組由置于轉(zhuǎn)子槽中的導(dǎo)條和兩端的端環(huán)構(gòu)成。為節(jié)約用鋼和提高生產(chǎn)率，小功率異步電動機(jī)的導(dǎo)條和端環(huán)一般都是融化的鋁液一次澆鑄出來的；對于大功率的電動機(jī)，由于鑄鋁質(zhì)量不易保證，常用銅條插入轉(zhuǎn)子鐵心槽中，再在兩端焊上端環(huán)?；\型轉(zhuǎn)子繞組自行閉合，不必由外界電源供電，其外形像一個(gè)籠子，故稱籠型轉(zhuǎn)子。黑龍江電機(jī)廠商</p><p
